This low toxicity, borax-based ant control system includes 32 ounces of bait — a whole summer's worth — plus two bait reservoirs that are weather-proof, spill-proof, and pet-safe. It's the same type of ant control system professionals use, at a fraction of the cost. Simply locate them around the perimeter of your house. Effective on sugar-feeding and protein-feeding ants, harvester ants, carpenter ants, even cockroaches.
